Alicia: OK. Let’s take a look at a little cardiac case and let’s see how this understanding plays out.

Q: Mrs. Plum has actually been diagnosed with left posterior tibial artery occlusion due to stenosis.

A: We’re going to do this in ICD-10- CM and ICD-9-CM. Why anatomical knowledge is so essential when you’re dealing with cardiac? Mrs. Plum has a left posterior tibial artery occlusion and it is because of stenosis. So, what are we going to search for first? We’re going to search for an occlusion, that’s what she has. What she is being seen for– an occlusion of her artery.

If you go in ICD-10 you’re going to look in the alphabetic index first, since when you’re searching for codes you constantly wish to go to the index initially and you’re going to look under occlusion. Now, for occlusion, it’s divided anatomically. You’ll have artery, you’ll have all different kinds of things that can be occluded, but we’re doing artery.

Now, if you do not understand where the tibial artery is– let’s state you have no concept what tibial artery is, then you can not code this diagnosis since you go to occlusion, you understand it’s an artery, however then it indexes into lower extremities due to stenosis or stricture. If you don’t understand that the tibial artery is next to the tibia in the lower leg, which is an extremity, a lower extremity, that’s all you get.
